Development of an index of aquifer water quality within GIS environment

Hussain, Hussain Musa; Joshi, H.; Singhal, D. C.; Kumar, S.; Rao, M. S. (Islamic Azad University, 2010)

The changes in human population often correspond with change in land use, including expansion of urban areas, agriculture and increasing industrialization, which necessitate increasing the available amount of drinking ...

Analyses of Observed and Anticipated Changes in Extreme Climate Events in the Northwest Himalaya

Singh, Dharmaveer; Jain, Sanjay K.; Gupta, Rajan Dev; Kumar, Sudhir; Rai, S. P.; Jain, Neha (MDPI, 2016)

In this study, past (1970-2005) as well as future long term (2011-2099) trends in various extreme events of temperature and precipitation have been investigated over selected hydro-meteorological stations in the Sutlej ...

Closure to New Methods for Aquifer Parameters from Slug Test Data

Singh, Sushil K. (American Society of Civil Engineers, 2012)

The writer is thankful to the discusser for the interest in the original paper and putting forward these viewpoints. A closure to another discussion on this paper has already been published. The discusser should refer ...

Groundwater Mound due to Artificial Recharge from Rectangular Areas

Singh, Sushil K. (American Society of Civil Engineers, 2012)

The suitability of the widely used existing solution for calculating groundwater mound due to artificial recharge from rectangular areas is examined for its applicability to unconfined aquifers, and this solution has been ...

Generalized Analytical Solutions for Alternate and Sequent Depths in Rectangular Channels: Nonuniform Velocity

Singh, Sushil K. (American Society of Civil Engineers, 2013)

Novel generalized analytical solutions, in closed form, of hydraulic-energy and hydraulic-force equations governing the flow in rectangular open channels are derived considering the nonhydrostatic pressure and nonuniform ...

Generalized Analytical Solutions for Alternate and Sequent Depths in Rectangular Open Channels: Sine Form

Singh, Sushil K. (American Society of Civil Engineers, 2015)

Two novel generalized analytical solutions of nondimensional specific energy and specific force equations for flow in rectangular open channels are obtained, which enable direct and explicit calculation of the alternate ...

Simple Parametric Instantaneous Unit Hydrograph

Singh, Sushil K. (American Society of Civil Engineers, 2015)

A new, simple, parametric instantaneous unit hydrograph (IUH) with conceptual and physical justification is proposed. The new IUH has only two parameters, one of which is the time base of the unit hydrograph, an obvious ...

Theme 5-1-Scenario analysis in water resources systems optimization under uncertainty conditions

Sechi, Giovanni M.; Zuddas, Paola (National Institute of Hydrology, 2000)

In this paper we present a methodology to perform water system optimization under climatic and hydrological uncertainty, in order to reach a sufficient degree of systems reliability to determine the risk of significant ...

Theme 5-2-Seasonal to interannual hydrologic prediction a case study from Sydney, Australia

Sharma, Ashish (National Institute of Hydrology, 2000)

Effective use of available water resources is a serious problem facing the world as it enters the 21st century. An increasing demand and an ever-uncertain supply in the form of precipitation is a cause of concern to water ...

Theme 5-3-A nonparametric approach for preserving interannualdependence in synthetic flow sequences.

Sharma, Ashish; O'Neill, Robert (National Institute of Hydrology, 2000)

The estimation of risks associated with alternate plans and designs for water resources systems requires generation of synthetic streamflow sequences. The mathematical algorithms used to generate these sequences at monthly ...

Theme 5-4-Temporal disaggregation of rainfall data using artificial neural networks.

Kumar, D. Nagesh; Raju, K. Srinivasa (National Institute of Hydrology, 2000)

Seasonal rainfall in many regions is influenced by global climatic parameters such as El Nino Southern Oscillation (ENSO), La Nina. Seasonal rainfall predictions are based on such Global climatic parameters. However, for ...

Theme 5-5-Rainfall-runoff relationship model for Amameh watershed in Iran.

Sadeghi, S. H. R.; Singh, J. K.; Das, Ghanshyam (National Institute of Hydrology, 2000)

The Amameh catchment in Iran that covers 3712 ha in area is one of the mountainous sub basins of Jajroud River over which the Latian dam has been constructed. There the mean annual precipitation is 848.4 mm. The mean annual ...

Theme 5-6-Development of regional flood frequency relationships using L moments for south Bihar.

Kumar, Rakesh; Chatterjee, C.; Kumar, Sanjay; Lohani, A. K.; Singh, R. D. (National Institute of Hydrology, 2000)

Estimation of magnitudes of likely occurrence of floods is of immense importance for solution of a variety of water resources problems. Whenever, rainfall or river flow records are not available at or near the site of ...

Theme 5-7-Severity-frequency-duration measures for urban water supply systems.

Perera, B. J. C.. (National Institute of Hydrology, 2000)

Urban water supply authorities are required to supply water to their customers (both bulk water customers and small users) with a certain level of reliability. Various indicators have been used in the past to measure the ...

Theme 5-8-Worth of extreme flood events in site specific flood frequency analysis.

Parida, B. P. (National Institute of Hydrology, 2000)

To obtain reliable at-site flood quantile estimates from a small sample of observations is a trivial exercise. To over come this problem, attempts to (i) use Probability Weighted Moment (PWM) method of parameter estimation ...

Theme 5-9-Simulation of soil moisture movement in a forested watershed.

Purandara, B. K.; Kumar, C. P. (National Institute of Hydrology, 2000)

Prediction of soil moisture retention and movement is very important for irrigation scheduling, crop planning, runoff estimation and drought monitoring. Application of numerical techniques provides estimates for different ...
